Which Vehicle Exhaust or Brake Cooling Hose Is Right for Your Shop?

Lightweight rubber tailpipe exhaust hose for home garages, single-bay shops, and small-vehicle service

The flexible exhaust hose that connects to your tailpipe and routes vehicle exhaust out of your home garage or single-bay shop. Built for the everyday reality of working on cars indoors — pulling exhaust away from the vehicle, through a garage door or vent opening, and out into clean air. Lightweight all-rubber construction with no wire reinforcement, so the hose flattens against door seals then springs back to round shape. Flared ends on each length connect to additional sections or wall fittings, so a single hose can run as long as your setup needs. Rated 0–375°F — handles continuous exhaust from passenger cars, small trucks, and light-duty vehicles.

Best for:

• Home garages and single-bay shops
• DIY mechanics and hobbyists working on cars indoors
• Carbon monoxide extraction from cars idling at the work area
• Passenger cars, small trucks, and light-duty vehicles
• Replacement hose for Crushproof Tubing, Plymovent, and similar residential garage exhaust kits

Why this hose:

• All-rubber construction — no wire or metal helix, flattens against door seals and springs back to round
• Resistant to heat, aging, gasoline, oil, and fumes
• Flared ends connect to additional sections or wall fittings — extend as needed
• Lightweight, easy to handle, position, and store between jobs
• Rated 0–375°F — continuous exhaust from passenger cars and light-duty vehicles

Sizes 2.5"–4" ID. All-rubber wire-free construction. Standard 11 ft stock lengths.

Equipment compatibility: Compatible with residential and light-duty garage exhaust kits, extension hoses, and wall connectors from Crushproof Tubing, Plymovent, and similar manufacturers. Fits standard passenger car and light truck tailpipes (2.5"–4" ID). Verify your tailpipe outer diameter before ordering.

Heavy-duty wire-reinforced rubber exhaust hose for multi-bay auto shops, dealership service bays, and fleet maintenance

The heavy-duty version of our Standard Garage Exhaust Hose, built for the daily wear of multi-bay shops, dealership service bays, and fleet maintenance operations. Same rubber construction as the Standard hose above, but with a wire-reinforcement helix that prevents kinking when the hose gets dragged across concrete, pulled around pneumatic equipment, or coiled onto reel systems between jobs. Built for the pro reality where multiple techs share the same exhaust extraction setup all day, every day. Larger 5"–6" diameters fit overhead reel systems and dual-port dealership setups. Rated 0–375°F — handles continuous exhaust from passenger cars, light trucks, and everyday gas-and-light-diesel shop work.

Best for:

• Multi-bay auto shops and pro repair garages
• Dealership service bays and OEM warranty operations
• Fleet maintenance and municipal vehicle service
• Vehicle exhaust extraction reel systems (overhead-mounted, drop-down arms)
• RV manufacturing and assembly line exhaust capture
• Replacement hose for Plymovent, Crushproof Tubing, Eurovac, Nederman, and similar pro shop systems

Why this hose:

• Wire-reinforced rubber construction — prevents kinking when dragged, coiled, or pulled around equipment
• Same heat / oil / fume resistance as our Standard Garage Exhaust Hose, with heavier-duty build for daily commercial use
• Larger 5"–6" diameters fit pro overhead reel systems and dual-port dealership setups
• Rated 0–375°F — covers passenger car, light truck, and standard diesel shop exhaust
• Easily reconnected and repositioned between bays
• Made in USA

Sizes 5"–6" ID. Wire-reinforced rubber construction. Standard 11 ft stock lengths.

Equipment compatibility: Compatible with vehicle exhaust extraction reel systems and shop-floor setups from Plymovent, Crushproof Tubing, Eurovac, Nederman, and similar manufacturers. Sized for pro multi-bay installations (5"–6" ID fits most overhead reel systems and dual-port dealership setups). Verify your system's intake diameter before ordering. For sustained high-temperature diesel exhaust above 375°F, see our High-Temperature / Diesel Exhaust Hose below.

Silicone-coated fiberglass exhaust hose for diesel shops, performance builds, and high-heat exhaust extraction

The flexible high-temperature exhaust hose built for environments where rubber gives up. Diesel exhaust runs hotter than gas — especially during cold-start, sustained load, and turbo cool-down — and standard 375°F rubber softens, deforms, and fails under continuous heat. Heat-Flex GS uses double-ply silicone-coated fiberglass construction with a steel wire helix, rated -65 to 600°F continuous, so it holds shape and strength under sustained engine heat. Built for diesel shops, performance and motorsports builds, engine test cells, and any high-temp vehicle exhaust extraction where the heat is more than rubber can take.

Best for:

• Diesel vehicle exhaust extraction — light-duty, medium-duty, and heavy-duty diesel
• Fleet diesel maintenance and Class 8 truck shops
• Performance builds and modified gas / turbo engines
• Engine test cells, dynamometers, and shop diagnostic stands
• Tractor pull, drag race, and motorsports engine exhaust
• Any vehicle exhaust application where 375°F rubber isn't enough

Why this hose:

• Silicone-coated fiberglass construction — rated -65 to 600°F continuous, higher than any rubber hose in our lineup
• Double-ply build with steel wire helix — holds shape under vacuum and sustained high temperature
• Resistant to oil, solvents, and most industrial chemicals
• Wide size range from small-engine extraction (1") up to large fleet and dyno systems (12")
• Continuous-temperature rated, not just intermittent peaks
• Mechanically reinforced — holds up under prolonged thermal cycling

Sizes 1"–12" ID. Double-ply silicone-coated fiberglass with steel wire helix. Standard 12 ft stock lengths.

Equipment compatibility: Compatible with diesel shop and pro garage exhaust extraction setups from Plymovent, Crushproof Tubing, Eurovac, Nederman, and similar manufacturers. Also fits dynamometer test cells, engine test stands, foundry exhaust runs, and motorsports installations. Verify intake diameter and continuous-temperature requirements before ordering. For sustained 600°F+ extreme exhaust applications (tractor pull, drag race), contact us about the Flex-Lok 1200 — rated to 1,200°F continuous in 4"–18" sizes.

Silicone brake ducting hose for motorsports, track-day, and performance brake cooling

The flexible brake cooling duct that routes cool air from front intakes to brake rotors and calipers, keeping pads and rotors below failure temperature during sustained track or race use. Silicone-coated fiberglass construction with a steel wire helix, rated -65 to 500°F continuous — handles the heat soak that radiates off hot brakes without softening or losing shape. Purpose-named for brake ducting (BDS = Brake Ducting Silicone). Available in sizes that match NACA duct, backing plate inlets, and brake hat scoops on most performance builds.

Best for:

• Motorsports, track-day, and HPDE brake cooling
• Performance street builds and restomod brake upgrades
• Endurance racing, autocross, and time-attack setups
• Replacement brake duct hose for OEM and aftermarket brake cooling kits

Why this hose:

• Silicone-coated fiberglass — rated -65 to 500°F continuous, won't soften under brake heat soak
• Steel wire helix holds shape under cornering loads and vibration
• Purpose-named brake ducting product — not a generic high-temp hose
• Wide size range fits most NACA duct outlets and brake backing-plate inlets

Sizes 2.5"–10" ID. Single-ply silicone-coated fiberglass with steel wire helix. Standard 12 ft stock lengths.

Equipment compatibility: Fits brake cooling installations across Brembo, AP Racing, StopTech, Wilwood, and OEM-style brake duct kits. Verify NACA duct outlet or backing plate inlet diameter before ordering.

Need heat-reflective performance? The Heat-Flex Raceflex uses a silver metallized laminate that reflects heat away from the hose wall — keeping cooling air actually cool to the rotor instead of warming through the duct. Rated to 625°F in race-spec 1.5"–3" sizes.

Heavy-wall rubber dyno cell exhaust hose for dynamometers, emissions testing, and engine test stands

The dyno cell exhaust hose built for capturing engine exhaust during dynamometer pulls, emissions testing, and engine test-stand work. Thicker-walled gray rubber construction rated to 450°F — the same Garage Exhaust product family as our pro shop hose, with extra heat tolerance for sustained engine load.
